The Flames signed Jonathan Aspirot to a one-year, two-way contract. Aspirot spent 2024 with the Calgary Wranglers (AHL), posting 33 points (6G / 27A) in 66 games. The 25-year-old undrafted defenseman will likely start 2025 with the Wranglers.

Aspirot was an undraafted free agent out of the QMJHL, who spent the 2019-20 season with the Senators AHL affiliate. The 20-year-old winger scored two goals with 14 assists (16 points) in 44 games with Belleville and will likely start the 2020-21 season with them again.
